Forgotten Realms: Demon Stone

It is set in the Forgotten Realms campaign setting for Dungeons & Dragons , but the gameplay only vaguely models D&D's structure. The first villain—Ygorl—is the leader of the Slaad army.Cireka, general of the Githyanki, is the second. The game's introduction explains that the only thing keeping each of them from taking over the realm is their hatred of each other. Once there, they unwittingly release Ygorl and Cireka from the Demon Stone and into the world. As he comes to the aid of wood elves captured by the orcs, a half-drow, half-elf named Zhai and a sorcerer named Illius join the battle. He says that they will need a new Demon Stone; one could be found in the possession of the Yuan-ti people. The three follow the warlords through the portal to the lair of Caminus.
